Andrew Krepinevich, Executive Director of the Center for Strategic and Budgetary Assessments, testifies before the Senate Armed Services Subcommittee on Emerging Threats and Capabilities: “There appears to be general agreement concerning the need to transform the US military into a significantly different kind of force from that which emerged victorious from the Cold and Gulf Wars. Yet this verbal support has not been translated into a defense program supporting transformation… the ‘critical mass’ needed to effect it has not yet been achieved. One may conclude that, in the absence of a strong external shock to the United States—a latter-day ‘Pearl Harbor’ of sorts—surmounting the barriers to transformation will likely prove a long, arduous process.”
[US Congress, 3/5/1999] This is very similar to what strategists at PNAC have said (see June 3, 1997).
